Wind Catching Systems, a Norwegian business, is working on the floating offshore wind power producer that might provide renewable energy to 80,000 houses at prices close to standard fossil fuels. The structure, dubbed the Windcatcher, would have over a hundred rotors piled vertically within a 300-meter-high framework. According to the business, one Windcatcher could create as much electricity as five of the world’s most powerful floating turbines while half the cost of the energy generated.
During the next 3 years, Wind Catching Systems plans to install the first structure. Wind Catching Systems Chief Executive Officer Ole Heggheim informed Dezeen, “Our goal is to allow offshore wind providers and developers to create power at a cost that is competitive with other sources of energy, without subsidies.” “We can create electricity at a cost per kilowatt comparable to what other floating technologies expect to attain in ten years.”
Unlike turbines built on fixed bases in shallow water, Floating turbines may capture electricity from greater winds that occur over the deep, open sea. However, because of their massive blades, which may reach 115 meters in length, these floating turbines are limited to wind speeds of roughly 11 meters per second.
Wind Catching Systems wants to increase the efficiency of floating wind farms by using a bigger quantity of smaller turbines with 15-meter-long blades that can do more rotations for every minute and capture higher winds of a maximum of 17 to 18 meters per second, creating more energy.
“The wind possesses an energy of around 350 watts for every square metre at 11 metres for each second,” Heggheim remarked. “And the wind contains an energy of about 13,000 watts for every square metre at 17 metres for each second, so we’re capturing wind’s exponential power.” 117 of such smaller turbines would be put within the steel framework and installed on the semi-submerged trimaran boat like a sail in the Windcatcher.
The sail would be attached to a rotating turret and able to turn in the wind’s direction. The Windcatcher might make use of the multirotor impact by positioning the turbines close together, allowing the turbulence established by one turbine to be caught by the surrounding ones, maximizing the amount of power they can produce. Heggheim noted, “There is a turbulence synergy between the rotors.” “A network of ten turbines will create more than ten individual turbines.” According to the business, one Windcatcher could provide enough energy to serve 80,000 homes while consuming 80% less surface area.
